Foro de Filatelia Argentina

My excuses for not writing in Spanish; I am trying to follow the threads in Spanish as they are at times most interesting!

Les pido disculpas por no escribir en español, Trato de seguir los hilos en español debido a que en general son mas interesantes.

The 1978 "Difusion de servicios" definitives consist of 3 values: 20p, 30p and 50p and were printed supposedly in photogravure. The types of paper used have also luminescence substances in the coating as mentioned in the catalogue. But that is not the most important thing about this issue.

La serie ordinaria "Difusion de servicios" del año 1978 consiste en 3 valores: 20p, 30p, y 50p y supuestamente fueron impresas mediante el proceso de fotograbado. Los tipos de papel utilizado tienen una capa de luminiscencia como se menciona en el catalogo. Pero eso no es lo mas importante de esta serie.

The later printings seem to have a rather pecular type of photogravure - or maybe it is offset-litho - that shows a very irregular corn instead of a regular photogravure screen. It is also much too early to see the electro-mechanical engraved printing that only started in 1982 with Belgian stamps! When you give it a good look you may see a regular screen in the middle of the printed, coloured field, but the edges are so irregular! Any suggestion of what this is very welcome.

Las impresiones más tardias parecen tener un tipo muy peculiar de fotograbado, quizas sea offset/litografiado, que muestra un grano muy irregular en lugar del tipico tramado regular del fotograbado. Es tambien muy pronto para ver la impresion mediante grabado electromecanico que comenzó en el año 1982 con estampillas Belgas. Mirando detalladamente quizas vean un tramado regular en el medio de la impresion ( en los colores plenos) pero los bordes son DEMASIADO irregulares. Cualquier opinion acerca de este detalle sera muy bienvenida



This definitive issue is not the last Argentinian definitive issue that has this type of screens. I will return to them later. I get the impression that these variants are completely overlooked by the Argentinian philatelists...

Esta serie no es la ultima entre los sellos ordinarios argentinos que presentan este tipo de tramado. Volveré a tratar el tema mas adelante. Tengo la impresion que este tipo de variantes son completamente ignoradas por los filatelistas argentinos







and in detail:

The 20pesos is still in the tradtional photogravure! That is this printing ....



The 30pesos and 50pesos have the irregular screen ...

The 1978 Postal Code defintives comes in several papers and printing methods (see previous message!).

La serie ordinaria de 1978, codigo postal, fue impresa en varios papeles y formas de impresion(Ver mensaje previo).

I would like to show a few ditties that at first sight may have been fly specks but on second thought seeing 3 of them made me think twice:
Queria mostrar algunas "particularidades" que a primera vista parecerian ser "mosquitos" pero luego de encontrar las mismas en 3 sellos diferentes, hacen pensar mas en una variedad de plancha.

I am presently active in the following tutorial discussions on Argentinian stamps - one thread had got started by A. Rubiera and two threads by me after having been activated by Antonio to study Argentinian postage stamps :

Dear Mr Rein, thanks a lot for your posting an welcome to our forum. I would try to translate your postings to spanish so everyone here can read it (Our common friend Tony will probably help in the task). Please keep in mind that english is not my native language so I would try to do my best, but some mistakes could happen.

Yours Faithfully
Luis

Thanks for your welcome!

English is not my native tongue either... I will try to use the Spanish terms as well when necessary

where are you from, Reik?

Bye

Good evening!

It is 18:47 in Leiden, The Netherlands.

My name is Rein Bakhuizen van den Brink and I am specialising in "postage stamps and printing techniques" for over 40 years now of which I have a monthly column in the leading Dutch Stamp Monthly 'Filatelie" for 26 years.

As printing techniques - mainly photogravure, paper types and kiss-die cuts for self-adhesives - are universal I can easily dive into the stamps of any country and prepare a specialist survey in practically no-time provided I can lay my hands on some material....

As to the "Postal Code" definitives (Difusión de servicios) I forgot the mention that the blue 20 pesos stamp also exist in the coarse photogravure version:









and also that other definitives of that period have both types too - at least for some values:










More of this in the "mini" definitives.......

In 1978 short set Postal Services the new type of photogravure printing [etching??) shows 2 different cylinders judging by the screen gauge: 70 lines/cm instead of 100 lines/cm as the 2 other values have.

70:



100:

I know it is a difficult subject!

Most stamps that are assigned "mate" in the circa 1976-1979 definitives have this different type of photogravure.

Or is it the type of paper that is causing the phenomenon and/or the way the photogravure cylinders have been prepared? It is certainly not accidental as several stamps only exist this way!

Why should the Casa de Moneda use such a paper that would make a mess out of beautiful design like those of mr E. Miliavaca???? And not only his!

One thing is clear already! What philatelists in Argentina call 'mate' is NOT just "mate" it is "tizado mate" vs "tizado brillante".

What I was searching for long enough was proof that photogravure cylinders had been used for both ways of printing! In order to do so you need the help of fly-speck philately and come up with identical though sometimes minte flaws in the cylinders that occur again!

t be continued....

The traditionally etched blue and black cylinders:



the differently etched [?] or printed [?] cylinders:



The fly-specks both have!





And idem on a different stamp in black:
